HttpResponseException thrown while using InsertAsync app in .NET Backend Mobile service

Firstly, I had this problem when RequestStatus value can not be transferred from the client to the Mobile Service during InsertAsync, which will be processed with a value of zero (the client - the mobile app) (server - Azure.NET Backend Mobile Service) Vo second, I also tried changing its value in the debugger for processing, but HttpResponseException was thrown anyway. Detailed error message:

{"Processing of the HTTP request resulted in an exception. Please see the HTTP response returned by the 'Response' property of this exception for details."}

at Microsoft.WindowsAzure.Mobile.Service.TableController`1.<InsertAsync>d__3.MoveNext()
